Q:How do the welding parts in the welding drawings of the machine parts indicate the technical requirements of the drawings?

Therefore, the medium carbon steel has the most extensive application in the medium strength level. Besides being used as building material, it is widely used in the manufacture of various mechanical parts. Welding: 1 the preheating is conducive to reducing carbon steel heat affected zone is the most

Q:Where are the hanging baskets for the building?

It is strictly prohibited to use hanging baskets as vertical transport facilities for personnel and materials; no staff member is allowed to climb from a basket to a B basket

Q:Where are the mechanical pressurization air supply facilities set up?

The purpose of setting up a mechanical pressurization air supply smoke prevention system is to provide evacuation routes and shelters without smoke interference in the event of a fire in the building. Therefore, in the closed door, pressing position, and the fire floor must maintain a certain pressure difference, the position of the air pressure value is a relative positive pressure); at the same time, in the open part of the pressure when the door can have enough air velocity in the opening section, to effectively prevent the intrusion of flue gas, the safety of personnel ensure evacuation and refuge.

Q:What is a door rack for a construction site? How high is it generally?

Door scaffolding has not yet unified design and product standards, the products of different specifications, quality is inconsistent. Not only for construction units to use and management of great difficulties, is not conducive to the promotion of applications, but also to the construction safety risks. Therefore, it is necessary to organize and issue a unified standard for door scaffolding

Q:The building electrical iron pipe and the pipe line fixing member connected to what is called, what is called the iron pipe and the 86 fixed part of tin

Q:What functions should be achieved in mechanical structure design?

The function of the mechanical structure is mainly realized by the geometry of the machine parts and the relative position between the parts. The geometry of a part is made up of its surface, and a part usually has a number of surfaces, some of which are in direct contact with the surface of other parts, and this part of the surface is referred to as the functional surface. The connecting part between the functional surfaces is called the join surface
